This inventionA relates to an improved vending machine, and the purposeof'jthe inf vention is .to provide` a machine of this char.- acteradaptedv for vending merchandise such as coatedv ice cream in variousforms, themachine includingr a refrigerationy construction to keep theconfection cold or rather-'ina frozen condition. .f f v.

Another purpose is Vto provide va vending machine comprising a casingwith compartments for the merchandise, together with a coinactuatecl'mechanism for permitting the discharge ofthe vmerchandise oneat a time,

that is to 'say whenthe proper denomination ofcoin is deposited: in themachine anarticle of merchandise is discharged, saidmechanism includingmeans for. checking the remainder of the merchandise, when one articleof mer,- chandise is dispensed;l Another purpose of lthe invention. is`the provision of a reiirigerating compartment having upperand'lower'shelves for the vsup-v port ot any su'itablefdry ice,preferably frozen carbon dioxideV therel being wires in -thererigerating"comp artment for lthe support v ot the shelves toinsuretheir rigidity.1

A `Vit'e'ature yoit 'theinfvention- .consists iinthe provision ofretainingwires' to keep the merchandise: in its position f;r thermerchandise :in the present instance being .in the Aorinfotpackages'containing perishable eatables,such

Y as frozen ice cream: andthe like,fand it is the aim to use thesewires'to, retain'thepackages one above the other uniormly,-so that theykcan be easily and conveniently dispensed. Y,

rIt is to bev understoodithat the particulars herein given are in novway limitative, and that while still keeping within thescopeY of theinvention, any desired modification of details and proportions maybeinade in the construction ofthe appliance according to circumstances..

vThe` inventiony comprises further features and 'combination of partstobe'hereinafter set forth, shown in the drawings and 'claimed'.v

Referring to the draWingafidentiies a' Inconstructing thecabinet'therinner case" ing isfitted withinthe outerca'singfrom the top,the top wall of the outer casing being the last kpart 'to be applied.This top wall. -or closing the space containing the material.llisfastenedin place by spot welding or the like'as shown rat 5. Theinsulating material ybetweenv the vbottom of the` outer casingjan'd thebottom of the article/chute 6`being in- -sertedpror to the insertion ofthe inner :andback is filled with the insulating material.

The innery casing is divided into three compartments, two sidecompartments' 7 and y` 'anintermediatecompartment, the sidey com'-.partments receiving the merchandiseas iden-v -tilied'at '9. YSuitablefwires 10,:are. streached or otherwisemounted -intheside`compart` ments adjacent vthe walls Iof the intermediate compartmentso as to retainv thegarticlesbf `merchandise in alignment oneabove theother, u

so that each article will beproperly dispensed.v The Ylower. ends oftheside lcompartments vare provided with super-imposed* rmerchan- Vcasing, then the space between the sides, `front f 4-disesiipportslland,12,theuppersiipports 190' fil 11 being spring tensioned at 13 attheir hinge connections, in such wise as to cause supports 11 to tiltdownward, when a coin trip detentV 14 is released. Springs 15 areprovided Connected to the supports 11 and being of sufficient tension toreturn the supports to their initial positions after they are allowed todrop, the springs 15 being connected to a rod 16- Y The cabinet isprovided with coin slots 17, from which the coin chutes 18 extend, thecoin chutes communicating with a coin receptacle or boX 19. The tripdetents 1st are mounted adjacent the coin chutes and are associated withelements 20, which are pivoted. at 2Oa and have heads 20h, located inthe passages of the coin chutes, so that when a coin is deposited in theslot it will engage with the head and thereby permit the support 11 todrop. When the trip detent is actuated, it cooperates with an articleretaining device 22 to keep the remaining articles from dropping. Y

V-Thelower supports 12 are also spring Vtensioned at 23 adjacent theirhinge mountings to return said supports to their initial positions. Thelower supports act to support the article` of merchandise in such wiseas to retard its tall to some extent. However the article ofmerchandiseafter being released trom the upper support 11, engages with the lowersupport and overcomes the tension oi the spring 23, allowing the4article of merchandise to drop into the article chute.

Arranged inthe intermediate compartment are shelves 24 and 25, thelatter4 being sup'- ported a substantial distance'above the tornier.These shelves 24 and 25 are constructed of some suitable metal open workand are adapted to support dry ice, such as frozen carbon dioxide forthe purpose of keeping the merchandise cold andl from perishing,

Y namely keeping the merchandise-in a Jfrozen condition The lower shelfis fastened at 27 to the supporting rods 28, which in turn are connectedto the lower shelf. Theupper shelf has handles29, whereby the twoshelves may be lifted and removed from theV intermediate compartment,when the closure 30. is opened, such being the case when it is necessaryto replenish the ice. 'j

f The invention having been set forth, what Y is claimed is:

1. A- vendin'g machine having a magazine for articles to be kdispensedand .provided with a coin chute for delivery of a coin into a coin-box,a spring tensioned' element'tor supporting the articlesin saidVmagazine, a detent pivotally mounted to support said member, a

rocking device pivotally mounted in the vending machine casing andhaving one end lying across the path of the coin in the chute, and inturn operatively connectedto the detent, j

whereby as a coin passes through the chute, it in turn operates therocking device and `with- 1pc/Less draws the detent from under thespring tensioned member, allowing an article to be delivered from themagazinesaid rockable device liaving its other end provided with meansfor engagement between the article being delivered and an adjacentarticle.

2.

Y 3. A vending machine comprising acabinet having a magazine for articles to be delivered, a: coin chute inthe cabinet and provided with a coin box, apivoted element operativelymounted in the cabinet having a head lying across the passage of thecoin chute to be engaged by a coin passing through the V4chute, one endof said element having means adapted to engage between-an article to bedelivered anda succeeding article, whenV the element is actuated by acoin, spring tensioned means actuated to deliver said article, a detentto support said spring tensioned means to support the article priorto'being delivered, and means connecting the detent and the element,whereby Yasthe element is Vac.- tuated to retain the succeedingarticles, the detent releases the spring tensioned means,

Y and means to return the spring tensioned means-toits initial articlevsupporting position, wherebythe detent may againV engage with t-hespring tensioned means.

4. A vending machine comprising a cabinet having a magazine lfor thereception of articles to be dispensed, a coin chuteV having a. coin boxin the cabinet, an oscillatory element mounted in the cabinet and havingmeans at one end positioned across the path of a coin, means at theother end ot the element adapted to engage between an article to bedelivered and a Vsucceeding article when the element is actuated, meansspring ten- Ysioned to deliver an article, a `detent.operativelyrengagedwith said spring tensioned means to support the article :priortc.its'delivery, and a Vconnection between the Vdetent and the' element,whereby as thejnieans at one end of the element engages between-anarticlev to be delivered and a succeeding article, '."f

said detent releases the kspring tensioned means allowing the article tobe delivered.

5. A vending machine comprising a cabinet having a magazine for thereception of 5. articles to be dispensed, a coin chute having a coin boxinthe cabinet, an oscillatory element mounted in the cabinet and havingmeans at one end positioned across the path of a coin, means at theother end of the elel@ ment adapted to engage between an article to bedelivered and a succeeding article when the element is actuated, meansspring tensioned to deliver an article, a .detent peratively engagedwith said spring tensioned means to support the article prior toitsdelivery, and a connectionl between the detent and the element,whereby as-the means at one end of the element engages between anarticle to be delivered and a succeeding article, said detent releasesthe spring tensioned means allowing the article to be de- Y livered, andspring means-to' overcome the spring tensioned means to return it to itsinitial holding position. n c In testimony whereof he aliixes hissignature. l JACOB I.
